De Gea was the subject of a lengthy transfer saga last summer amid strong interest from Madrid but a deal collapsed on the final day of the Spanish transfer window due to late paperwork.
The Spaniard then went on to sign a new deal at Man United but AS claim that the contract included a clause which states that Madrid can sign De Gea for £39m — but only before June 15.
United would be free to put whatever price they wish on De Gea should the deadline pass without action.
De Gea was seconds away from sharing the Premier League’s Golden Glove award with Arsenal’s Petr Cech but a late own goal from Chris Smalling in the 3-1 win over Bournemouth on Tuesday meant the keeper was robbed of the honour.
De Gea has undoubtedly been the shining light of United’s season and he is arguably the squad’s only world-class player. Supporters will be hoping the excellent form of Madrid’s Keylor Navas will persuade the Spanish club to leave their pursuit of De Gea for now.
